DRINKING-CUP.

Bpeoication of Letters Patent. Patented Sept, 16, 1913,

l Application tiled October 24, 1910. Serial No. 588,644.

To all whom t may concern:

Be it known that I, S/rEnmNe Enmo'rr, residing at Newton, in the countof Middlesex and State of Massachusetts, lave invented an Improvement inDrinking-Cups, of which the following is a specification.

This invention has reference to paper drinking-cups designed to be usedonce and then destroyed.

The cup embodying this invention generally speaking is composed of asingle sheet of paper comprising a body-portion having a plurality ofslits at its lower edge to forni tabs, said body-portion being bent intocylindrical form to produce the body of the cup, and said tabs beingturned in and overlapped to form the bottom closure. The tabs are bentinward or folded on a chord of the arc of the body so that the top ofthe cup is circular and the bottom is angular, preferably square. Inorder that the bottom of the cup shall be tight when coated withparaffin-wax it is necessary. that it shall be substantially tightbefore the wax is applied, and considerable diiliculty is encountered inconstructing and arranging the tabs along the lower edge of thebody-portion of the sheet whereby this result may be obtained. The maintrouble occurs at the lower end of the side sea-1n of the body-portion,for if a space between the tabs is formed at this point by reason ofirregularly or unevenly overlapping the side edges of the sheet whenforming the side seam, such space cannot be subsequently filled withwax. I have discovered that by so slitting the end of the sheet that atab is produced at the lower end of the side seam this trouble isobviated. This tab may-be formed by providing narrow tabs at each e-ndof the bodyportion, the outer side edges of which are in continuation ofthe side edges of the body-portion, then when the side edges of thebody-portion are overlapped and adhesively secured the outer side edgesof these end tabs may be overlapped and adhesively secured and the sideseam thus continued uninterruptedly across the middle of the bottom ofthe cup. While slight variations in securing the side edges of thebody-portion will result in corresponding variations in the width of thetab thus formed, no space will be produced.

Therefore, my invention has for its object the construction of a cupfrom a single piecey of paper comprising a body-portion and a glurahtyof tabs along its lower edge, the en tabs of which are made narrow andthe outer side edges of which are in continuation of the side edges ofthe body-portlon of the blank, so that when the bodyportion is bent toform the body of the cu and its slde edges are overlapped and a hesivelysecure together the outer side edges of said end tabs will be overlappedand adhesively secured, thereby to form a tab at the lower end of theside seam of the cup, said seam thus continuing uninterruptedly acrossthe bottom of the cup'.

igure 1 is a side elevation of a cup embodying this invention. Fig. 2'isa plan View of the cup. Fig. 3 is an underside vlcw of the cup. Fig. 4is an enlarged vertical section of the bottom of the cup. Fig. 5 is aview of the blank of which the cup may bc composed.

The blank of which the cup is composedV is cut from a sheet or strip ofpaper, and has a body portion a of large area designed to form thehollow cylindrical body, andhas tabs a', a2, a3, a4, a, at its loweredge, the end t-abs a and a being made narrow as compared with the othertabs and having their outer side edges in continuation of the side edgesof the body portion.

The tabs are here shown as formed by slitting the lower edge of theportion a, and when so formed they are contiguously disposed. Thismanner of forming the tabs is referred, but my invention is not limiteto so forming them.

The blank is placed on a suitable form and its opposite side edgesoverlapped and secured together by glue, or other adhesive substance.When securing said edges to` get-her the outer side edges of the endtabs a and a are also overlapped and adhesively secured together, toform a single tab. The single tab thus produced is located at the end ofthe side seam of the cup body, said seam extending uninterruptedly tothe end `.yard on a chord of the arc of the cylindrical body, and, ashere shown, four tabs being provided, four lilies of fold will beformed, at right angles to each other, hence the bottom of the cup issquare. A greater or less number ot tabs will result in the formation otan angular bottom of a correspondingly different shape. Said inwardlyextended or folded tabs overlie one another and form a bot-tom closurecomposed of several superposed layers, and the superposed tabs aresecured together by an adhesive substance.

As here shown, one of the tabs as a3 is made coextensive with the areaof the bottom and serves as a main closing tab and as the bottom is hereshown as square, said tab has parallel sides; and the two part tab o. o,is folded inward upon said tab z2-and being made ot' t-Wo parts,overlapped and adhesively secured together longitudinally and therebystitlened, yserves as a stiliener for the bottom. The end tabs a and awhich form said single tab have parallel sides as shown in Fig. 5, sothat `when overlapped and secured together the single tab thus formedhas parallel sides, and, like the tab a3 is made to extend oversubstantially the entire bottom opening. The intermediate tabs a2 and a4extend over each other and over the aforesaid tabs and 'hold them,especially until finally set by coated interiorly or exteriorly, eitheror both, the cup is waterproof and the bottom sealed. )r waxed orWax-coated paper may be eniployed in forming the cup, and in such easeit will not need to be inally coated with Wax, although a final coatingis desirable.v

at least around the bottom, to close and `seal gether with the tabsforming its bott-om-y closure being composed of a single sheet of papercomprising a body-portion havingv a plurality of slits at its lower edgeto form a row ot tabs which tabs are adapted to be turned in andoverlapped to form the bot-- tom closure, each intern'iediate tabof therow being made as Wide as and forming one side of the bottom of the cupand each end tab being made narrower than the intermediate tabs andhaving its outer side edge in continuation of the side edge of thebody-portion, said narrow tabs overlapping one another and beingadhesively secured together when the side edges of the sheet areoverlapped and adhesively secured, thus forming a single two-piece tabat the lower end of the side seam which is as Wide as and forms one sideof the bottom of the cup.

ln testimony whereof, I have signed my name to this specification, inthe presence of two subscribing Witnesses.
